Glacier Weather and Spare Days: Planning a Campervan Trip Around Cancellations

Quick summary: The single most useful tip for a campervan glacier trip is to build in a spare day. Glacier flights, heli-hikes and skydives all depend on clear weather, and the West Coast is one of the wettest places in New Zealand, so cancellations are common. With a campervan or motorhome, you can stay an extra night and try again, book your experience for the first morning, and fill a wet day with hot pools, rainforest walks and wildlife. This guide explains how.

Why do glacier flights get cancelled so often?

Because the Southern Alps make their own weather. Moist air from the Tasman Sea rises over the mountains and drops heavy rain on the West Coast, and cloud often wraps the high peaks even when the coast is dry. Helicopters and planes need clear visibility to fly safely among the mountains and land on the snow, so pilots won’t fly when cloud is low or winds are strong. It’s a matter of safety, and operators are cautious.

How do you plan around the weather?

1. Allow two or three nights at Franz Josef, Fox or Mount Cook.
2. Book your flight or heli-hike for the first morning, so the second is a back-up.
3. Check the forecast each evening, and talk to the operator about the chances for the next day.
4. Keep your onward plans flexible, so you can stay longer if needed.
5. Have a wet-day plan, so a cancellation doesn’t waste the day.

Is an extra night at the glaciers easy to arrange in an RV?

Usually, yes. Outside the busiest summer weeks, holiday parks in Franz Josef and Fox can often extend your stay at short notice, and the flexibility of a campervan is one of its great advantages here. In peak periods, book an extra night in advance and keep the following night’s booking flexible.

What can you do on a wet day?

• Soak in the hot pools in Franz Josef’s rainforest.
• Visit the wildlife centre to see rowi kiwi.
• Walk in the rainforest, which is at its most atmospheric in the rain, with waterfalls in full flow.
• Kayak on Lake Mapourika, which can often go ahead in light rain.
• Take a nature tour. See nature and wildlife.

Are mornings better for flying?

Often. On many days, the mountains are clearest early, before cloud builds. Morning flights are popular for this reason, so book early and arrive at the base on time. That said, West Coast weather changes quickly, and afternoons sometimes clear after a cloudy morning.

Is the weather different at Mount Cook?

Often, yes. The eastern side of the Alps is drier and sunnier, though strong nor’west winds can bring cloud to the peaks and ground flights there too. If the West Coast is wet for several days, Mount Cook may be clearer, and the reverse. See Mount Cook to the West Coast.

What about the roads?

Heavy rain can cause slips and flooding that close West Coast highways, including the Haast Pass, for hours or sometimes longer. Check road conditions before driving, and allow flexibility in your plans. See driving the West Coast.

What happens if your flight is cancelled?

Operators normally offer to rebook you on a later flight or refund you. Check the cancellation policy when you book, and give the operator a mobile number so they can contact you.
